with in my expectation, used in sports field doesnt mean its top-end. a top-end garment is not only consists of excellent quality (obviously, and easy to achieve, considering making T-shirt is one of the easiest things to to apart from socks..lol) but also the technologies applied on making that garment which will make them standout from similar products. to make a top-end t-shirt the most difficulty part is the printing and washing techniques and effects (italy dominates the field, even Japan is in no place to challenge that)
